Why is my Gree KFR-25x2GW/NaJ31F-K Air Conditioner's cooling or heating not working well?

  Jacqueline OrtizAug 13, 2025
  There could be several reasons why your Gree Air Conditioner isn't cooling or heating efficiently. Check the following: Is the set temperature suitable for the room? Are the air inlet or outlet obstructed? Are the air filters dirty? Are all windows and doors closed properly? Is the indoor fan speed set to low? Is there another heat source in the room?
